A stop key 2015 serves to stop an operation in operation. The ID key 2016 is used when inputting the user ID of the user. A reset key 2017 is used when initializing settings from the operation unit.

Scanner Image Processing Unit The configuration of the scanner image processing unit 2080 is shown in FIG. The image bus I / F controller 2081 is connected to the image bus 2008 and controls the bus access sequence and generates control and timing of each device in the scanner image processing unit 2080. The filter processing unit 2082 performs a convolution operation with a spatial filter.

Control. The processing procedure of the image compression processing unit is shown below.

  Settings for image compression control are performed from the CPU 2001 to the image bus I / F controller 2041 via the image bus 2008. With this setting, the image bus I / F controller 2041 performs settings necessary for image compression (for example, MMR compression and JBIG expansion) for the image compression unit 2043. After performing the necessary settings, the CPU 2001 again permits image data transfer to the image bus I / F controller 2041. In accordance with this permission, the image bus I / F controller 2041 starts transferring image data from each device on the RAM 2002 or the image bus 2008. The received image data is temporarily stored in the input buffer 2042, and the image is transferred at a constant speed in response to an image data request from the image compression unit 2043. At this time, the input buffer determines whether image data can be transferred between the image bus I / F controller 2041 and the image compression unit 2043, reads the image data from the image bus 2008, and reads the image compression unit 2043. When it is impossible to write an image on the screen, control is performed so as not to transfer data (hereinafter, such control is referred to as handshaking). The image compression unit 2043 temporarily stores the received image data in the RAM 2044. This is because several lines of data are required depending on the type of image compression processing to be performed, and several lines of image data are prepared in order to compress the first one line. This is because the image cannot be compressed unless it is empty. The image data subjected to the image compression is immediately sent to the output buffer 2045. The output buffer 2045 performs handshaking with the image bus I / F controller 2041 and the image compression unit 2043 and transfers the image data to the image bus I / F controller 2041. The image bus I / F controller 2041 transfers the transferred compressed (or expanded) image data to each device on the RAM 2002 or the image bus 2008. Such a series of processing is repeated until there is no processing request from the CPU 2001 (when processing of the necessary number of pages is completed) or until a stop request is issued from this image compression unit (when an error occurs during compression and expansion). It is.

Image Rotation Unit The configuration of the image rotation unit 2030 is shown in FIG. The image bus I / F controller 2031 is connected to the image bus 2008 to control the bus sequence, control to set a mode or the like in the image rotation unit 2032, and timing to transfer image data to the image rotation unit 2032 Take control. The processing procedure of the image rotation unit is shown below.
Settings for image rotation control are performed from the CPU 2001 to the image bus I / F controller 2031 via the image bus 2008. With this setting, the image bus I / F controller 2041 makes settings necessary for image rotation (for example, image size, rotation direction / angle, etc.) to the image rotation unit 2032. After performing the necessary settings, the CPU 2001 again permits image data transfer to the image bus I / F controller 2041. In accordance with this permission, the image bus I / F controller 2031 starts transferring image data from each device on the RAM 2002 or the image bus 2008. Here, the size is 32 bits and the image size to be rotated is 32 × 32 (bits), and when transferring image data on the image bus 2008, image transfer is performed in units of 32 bits ( The image to be handled is assumed to be binary).

  As described above, in order to obtain a 32 × 32 (bit) image, it is necessary to perform the above unit data transfer 32 times, and it is necessary to transfer image data from discontinuous addresses (see FIG. 11). ).

  The image data transferred by the discontinuous addressing is written in the RAM 2033 so that it is rotated at a desired angle at the time of reading. For example, if the rotation is 90 degrees counterclockwise, the 32-bit image data transferred first is written in the Y direction as shown in FIG. By reading in the X direction at the time of reading, the image is rotated.

  After the 32 × 32 (bit) image rotation (writing to the RAM 2033) is completed, the image rotation unit 2032 reads the image data from the RAM 2033 by the above-described reading method, and transfers the image to the image bus I / F controller 2031.

  The image bus I / F controller 2031 that has received the rotated image data transfers the data to each device on the RAM 2002 or the image bus 2008 by continuous addressing.

  Such a series of processing is repeated until there is no processing request from the CPU 2001 (when processing of the required number of pages is completed).

Device I / F Unit The configuration of the device I / F unit 2020 is shown in FIG. The image bus I / F controller 2021 is connected to the image bus 2008, and controls the bus access sequence and generates control and timing of each device in the device I / F unit 2020. In addition, control signals to the external scanner 2070 and printer 2095 are generated. The scan buffer 2022 temporarily stores the image data sent from the scanner 2070 and outputs the image data in synchronization with the image bus 2008. The serial-parallel / parallel-serial conversion 2023 arranges the image data stored in the scan buffer 2022 in order or decomposes and converts the image data into a data width that can be transferred to the image bus 2008. The parallel-serial / serial-parallel conversion 2024 decomposes the image data transferred from the image bus 2008 or arranges the image data in order, and converts the image data into a data width that can be stored in the print buffer 2025. A print buffer 2025 temporarily stores image data sent from the image bus 2008 and outputs the image data in synchronization with the printer 2095.

  The processing procedure at the time of image scanning is shown below. The image data sent from the scanner 2070 is stored in the scan buffer 2022 in synchronization with the timing signal sent from the scanner 2070. When the image bus 2008 is a PCI bus, when the image data is 32 bits or more in the buffer, the image data is sent from the buffer to the serial-parallel / parallel-serial conversion 2023 in the first-in first-out manner. Is transferred to the image bus 2008 through the image bus I / F controller 2021. When the image bus 2008 is IEEE1394, the image data in the buffer is first-in-first-out, sent from the buffer to the serial-parallel / parallel-serial conversion 2023, converted into serial image data, and then converted into serial image data through the image bus I / F controller 2021. Transfer on 2008.

  The processing procedure at the time of image printing is shown below. When the image bus 2008 is a PCI bus, 32-bit image data sent from the image bus is received by the image bus I / F controller, sent to the parallel-serial / serial-parallel conversion 2024, and the number of input data bits of the printer 2095 Are stored in the print buffer 2025. When the image bus 2008 is IEEE1394, the serial image data sent from the image bus is received by the image bus I / F controller, sent to the parallel serial / serial / parallel conversion 2024, and the number of input data bits of the printer 2095 is determined. It is converted into image data and stored in the print buffer 2025. Then, in synchronization with the timing signal sent from the printer 2095, the image data in the buffer is sent to the printer 2095 in a first-in first-out manner.

  Each application described below can determine the characteristics of the delivery destination based on the information described in the above address book 4051.

  The Address Book can be edited, and can be downloaded and used, or directly referenced, stored in a server computer or the like in the network.

Remote Copy Application The remote copy application discriminates resolution information that can be processed by the device designated as the delivery destination from the Address Book 4051, and compresses the binary image read by the scanner using a known MMR compression. It is converted into a known TIFF (Tagged Image File Format), passed through the SLM 4103, and transmitted to the printer device on the network. Although not described in detail, the SLM 4103 is a kind of network protocol including device control information called a known Salutation Manager (or Smart Link Manager).

Broadcast distribution application Unlike the remote copy application, the broadcast distribution application can transmit images to a plurality of distribution destinations by one-time image scanning. Further, the distribution destination is not limited to the printer device, but can be directly distributed to a so-called server computer.

  If the destination device determines that the well-known network printer protocol LPD (Line Printer Daemon) and the well-known LIPS can be processed as a printer control command from the Address Book 4051, the image reading is similarly performed according to the image resolution determined from the Address Book 4051. In this embodiment, the image itself is compressed using a well-known FBE (First Binary Encoding), further LIPS-coded, and transmitted to the counterpart device using the LPR which is a well-known network printer protocol.

  If the delivery destination device is communicable with the SLM and is a server device, the address book 4051 is used to determine the server address and the folder in the server, and the binary image read by the scanner is read in the same way as the remote copy application. It is possible to compress using known MMR compression, convert it into a known TIFF (Tagged Image File Format), and store it in a specific folder of a server device on the network through the SLM.

  In the device of this embodiment, when the server as the counterpart device determines that a known JPEG-compressed multi-valued image can be processed, an image obtained by multi-value reading similar to the above-described binary image is used. Using compression, it is also possible to convert to a known JFIF and store it in a specific folder of a server device on the network through the SLM.

  When the delivery destination device is a known E-Mail server, the e-mail address described in Address Book 4051 is determined, the binary image read by the scanner is compressed using a known MMR compression, A TIFF (Tagged Image File Format) is used, and a known SMTP (Simple Mail Transfer Protocol) 4153 is transmitted to the E-Mail server.

  When data is set and acquired from each DocumentManager to the DIS database, the internal data format of DIS is based on the Control API. Therefore, mutual conversion between the data format conforming to the Control API and the data format understood by each DocumentManager is possible. Process. For example, when setting status data from each DocumentManager, device-specific data is interpreted, converted into corresponding data defined by the Control API, and written to the DIS database.

  When data is set and acquired from the JobManager to the DIS database, no data conversion occurs between the JobManager and the DIS.

  In the DIS, event data is updated based on various event information notified from the DocumentManager.

  FIG. 15 shows various databases (hereinafter referred to as DB) held in the DIS, and each DB will be described. A rounded rectangle in FIG. 15 represents each DB.

  7201 is a superviser DB, which holds status and user information about the entire device, and holds information that needs to be backed up, such as a user ID and password, in an HD device or a non-volatile storage device such as a backup memory. Is done.

  Reference numeral 7202 denotes a Scan Component DB, and reference numeral 7203 denotes a Print Component DB. These Component DBs are held corresponding to each existing component. For example, in the case of a device consisting only of a printer, only the PrintComponentDB exists, and for example, in the case of a device equipped with a FAX, the FAX ComponentDB is held. In each ComponentDB, the corresponding DocumentManager sets the function and status of the Component at the time of initialization.

  Reference numeral 7204 denotes a ScanJobServiceDB, and 7205 denotes a PrintJobServiceDB. These JobServiceDBs, like ComponentDB, set functions that can be used by the corresponding DocumentManager at the time of initialization, and their support status.

  Next, JobDB and DocumentDB will be described. Reference numeral 7206 denotes a ScanJobDB, 7207 denotes each JobDB of the PrintJobDB, 7208 denotes a ScanDocumentDB, and 7209 denotes a PrintDocumentDB.

  JobDB and DocumentDB are dynamically secured and initialized by JobManager each time a job and its accompanying document are generated, and necessary items are set. Each DocumentManager reads out items necessary for processing from JobDB and DocumentDB before starting processing of Job, and starts Job. After that, when the job is finished, these jobs and the DB of the document associated therewith are released. Since Job has one or more Documents, a plurality of DocumentDBs may be secured for a certain Job.

Reference numeral 7210 denotes a database holding event information notified from each document manager, and 7211 denotes a counter table for recording the number of scans and the number of prints of the apparatus.
Events notified from Document Manager include Component status transition from Scan Document Manager, Scan processing operation completion and various errors, Component Status transition from Print Document Manager, Print processing operation completion, paper jam, paper feed cassette open, etc. The event ID for identifying each event is determined in advance.

  When an event is issued from the DocumentManager, the DIS registers the event ID issued in the event database 7211 and, if necessary, detailed data associated with the event. In addition, when the cancellation of the event is notified from the DocumentManager, the event data designated to be deleted is deleted from the event database 7211.

  When an event is polled by the job manager, the DIS refers to the event database 7210, returns the event ID currently generated and detailed data associated with the event to the job manager if necessary, and if no event has occurred. Reply to that effect.

  Further, when the event of the completion of the scan processing operation and the completion of the print processing operation is notified, the counter value of the user who performed the scan and print is updated. This software counter is written back each time the value is updated in the backed-up memory device or the non-volatile storage device of the HD device so that the value is not lost due to accidental power interruption or the like.

Scan Operation Details of the scan operation will be described below. FIG. 16 is a conceptual diagram of blocks related to the scanning operation. A CPU 8101, a memory 8102, an image compression / decompression board 8104, a scanner 8107, and a SCSI I / F circuit 8103 that provides an I / F for connecting this system are connected to the PCI bus 8105. A SCSI I / F circuit 8103 and a scanner (or a scanner function unit of a copier having a composite function) 8107 are connected by a SCSI interface cable 8106.

  Further, an IDE controller 8108 is connected to the PCI bus 8105, and is connected to an IDE hard disk 8110 via an IDE cable 8109. FIG. 17 shows a software structure related to the scan operation. The JobManager 8201 has a function of classifying and storing application level requests.

  The DIS8202 stores parameters necessary for the scanning operation from the application level. A request from the application is stored in the memory 8102. The scan operation management unit 8203 acquires information necessary for scanning from the job manager 8201 and the DIS 8202. The scan operation management unit 8203 receives the job number / document number table data 8301 of FIG. 18 from the job manager 8201, and receives a scan parameter 8302 from the DIS 8202 based on the job number / document number table data 8301. As a result, scanning is performed based on the scanning conditions requested by the application.

  The scan operation management unit 8203 passes the scan parameters 8302 acquired from the DIS 8202 to the scan sequence control unit 8204 in the order of document numbers. Upon receiving the scan parameter 8302, the scan sequence control unit 8204 controls the SCSI control unit 8207 in accordance with the content of the scan image attribute 8308. Accordingly, by operating the SCSI controller 8103 connected to the PCI 8105 in FIG. 16, a scan is executed by sending a SCSI control command to the scanner 8107 via the SCSI cable 8106. Scanned images are stored in the SCSI controller 8103 via the SCSI cable 8106 and further stored in the memory 8102 via the PCI 8105. The scan sequence control unit 8204 compresses the scan image stored in the Memory 8102 according to the content of the scan image compression format 8309 of the scan parameter 8302 when the scan is completed and the image is stored in the Memory 8102 via the PCI 8105. Therefore, a request is issued to the compression / decompression control unit 8205. The compression / decompression control unit 8205 that has received the request uses the CODEC 8104 connected to the PCI 8105 to perform compression according to the designation of the scan image compression format 8309 from the scan sequence control unit 8204. The compression / decompression control unit 8205 stores the compressed image in the Memory 8102 via the PCI 8105.

  When the compression / decompression control unit 8205 compresses the scan image into the format specified by the scan image compression format 8309 and stores it in the Memory 8102, the scan sequence control unit 8204 stores the scan image in the Memory 8102 according to the image file type 8307 of the scan parameter 8302. File compressed compressed images. The scan sequence control unit 8204 requests the file system 8206 to create a file in the file format specified by the image file type 8307 of the scan parameter 8302. The file system 8206 converts the compressed image stored in the Memory 8102 into a file according to the image file type 8307 from the scan sequence control unit 8204, transfers the file to the IDE Controller 8108 via the PCI 8105, and transfers the IDE Hard Disk 8110 via the IDE Cable 8109. The scanned compressed image is converted into a file by transferring to. When the file system 8206 stores the image filed in the IDE Hard Disk 8110, the scan sequence control unit 8204 sends back a scan end notification to the scan operation management unit 8203, assuming that one current process on the Scanner 8107 has ended. .

  At this time, if there is a document that has not been scanned on the scanner 8107 and a scan request is issued from the job manager 8201, the scan operation is again performed by the scan sequence control unit using the scan parameter 8302 stored in the DIS 8202. Request.

  If there is no unscanned document on the Scanner 8107, or if there is no scan request from the JobManager 8201, a scan end notification is issued to the JobManager 8201, assuming that the scan operation has ended.

Printing Operation The printing operation will be described in detail below.

  FIG. 19 is a conceptual diagram of blocks relating to the printing operation. A CPU 9001, a memory 9002, an image compression / expansion board 9004, a printer 9007, and an engine I / F board 9003 that provides an I / F for connecting this system are connected to the PCI bus 9005. An Engine I / F board 9003 and a printer (or a printer function unit of a copier having a composite function) 9007 are connected by an engine interface cable 9006.

  The Engine I / F board has a DPRAM inside, and through this DPRAM, parameter setting to the printer, reading of the printer status, and exchange of print control commands are performed. The board has a video controller, and transmits image data developed on the PCI to the printer via the engine interface cable in accordance with VCLK (Video Clock) and HSYNC given from the printer via the engine interface cable. The timing of this transmission is shown in FIG. VCLK continues to come out and HSYNC is given in synchronization with the start of one line of the printer. The video controller reads data for the set image width (WIDTH) from the set memory (SOURCE) on the PCI and outputs it to the engine interface cable as a video signal. After repeating this for the designated line (LINES), an IMAGE_END interrupt is generated.

  As described above, when a print job instruction is passed from the application program on the CPU to the Control API, the Control API passes this to the controller-level JobManager as a job. Furthermore, this JobManager stores the job settings in the DIS and instructs the PrintManager to start the job. When the PrintManager receives a job, it reads information necessary for job execution from the DIS and sets it in the printer via the Engine I / F board and DPRAM.

  FIG. 21 shows setting items of the Engine I / F board, and FIG. 22 shows setting items, control commands, and status commands via the DPRAM of the printer.

  For the sake of simplicity, the operation will be specifically described assuming that this job is a non-compressed, letter (11 "x8.5") size binary image, two pages, one copy, and a printer having 600 dpi performance.

  First, when receiving this job, PrintManager calculates the number of image bytes of the width of this image (in this case, “8.5” side).

    WIDTH = 8.5 × 600 ÷ 8≈630 (Bytes)

  Next, the number of lines is calculated.

LINES = 11 × 600 = 6600 (Lines)
These calculated values and the SOURCE address storing the given first page image are set in WIDTH, LINES, and SOURCE shown in FIG. At this point, the Engine I / F board is ready for image output, but the HSYNC signal from the printer does not come (VCLK is coming) and no image data is being output.

  Next, PrintManager writes 1 as the number of output copies to a predetermined address (BookNo) of the DPRAM shown in FIG. After that, an output paper feed request (FEED_REQ) for the first page is issued, and an IMAGE_REQ from the printer is awaited. When IMAGE_REQ is received from the printer, IMAGE_START is issued. In response to this, the printer starts to issue HSYNC, and the Engine I / F board waiting for HSYNC outputs an image. When the printer detects the trailing edge of the output paper, it outputs IMAGE_END, and when the output paper is discharged, it outputs SHEET_OUT. The PrintManager receives IMAGE_END of the first page, sets WIDTH, LINES, and SOURCE of the second page to the Engine I / F board, issues FEED_REQ, and waits for IMAGE_REQ. The operation after the IMAGE_REQ of the second page comes is the same as that of the first page.

[Automatic data correction]
Next, a means for automatically correcting a file from an output sheet, which is the center of the present invention, will be described. FIG. 23 shows an example in which the user designates a correction location with a marker on the output paper. The upper right part of the figure is a photographic image, and the others are printed with text images. In this embodiment, description will be given of a flow in which handwritten correction information is fed back to a file with respect to a text image in the drawing and corrected data is output. In the present embodiment, a correction instruction is given to the portion “ABC” in the drawing.

  When print correction output mode setting (not shown) is performed on the operation unit 2012 and then the output sheet is read by the scanner 2070, first, image data is developed in the RAM 2002 via the scanner image processing unit 2080. In this process, the editing unit 2083 in the scanner image processing unit 2080 recognizes the area filled with the marker pen, and the position information of the character data to be corrected is extracted.

  Here, the CPU 2001 executes OCR software on the bitmap data on the RAM 2002 corresponding to the position corresponding to the position information painted with the marker pen stored in the editing unit 2083. First, the CPU 2001 cuts out characters in the text portion as shown in FIG. Next, the CPU 2001 performs character recognition of the cut out part, generates text information, and causes the operation unit 2012 to display the generated text information. FIG. 25 shows an example of the screen display. The user can edit and correct text data using the keyboard on the screen. By pressing the “OK” button, the text information is replaced with text data input from the keyboard.

  The system needs to identify the file to be modified as soon as it knows what to modify. FIG. 14 shows a situation in which JOB information is left as a watermark in a part of a figure when print output is performed before correction. The watermark information is a minute pattern that cannot be confirmed visually by the user, but when it is read by the scanner 2070, the PC, IP address, file name, page number, etc. output based on the read information can be known. Yes. As a watermark pattern and a recognition method, a digital watermark technique that is generally put into practical use may be used. After the information is obtained by reading the watermark, the file to be corrected is specified by comparing with the history of the JOB that has already been printed out. Normally, spool data at the time of print output is temporarily stored in the HDD 2004 and deleted after being rasterized by the raster image processor (RIP) 2060. However, there is a possibility of correcting data as in this embodiment. In the case where there is, the configuration is such that the data is left on the HDD 2004 together with the management information of the JOB by the designation at the time of output on the PC.

  By the above means, a file in which specific spool data exists on the HDD 2004 is specified, and preparations for reflecting the handwritten correction content in the specific file with respect to the correction target character are made. Based on this, the CPU 2001 corrects data in the specific file. FIG. 27 shows a portion in which text data is stored in spool data in a specific file determined from watermark information (actually formed by a code corresponding to the text information). First, a pattern matching the text data extracted by OCR is searched from the data string as shown in FIG. When there is only one pattern corresponding to the search, the text data edited on the editing screen in FIG. 25 is transferred to the RAM 2002 at the timing when the “OK” key is pressed, and then the specific file previously expanded on the RAM 2002 is stored. Replace the relevant part. FIG. 28 shows a state of the data string when the text data “ABC” before correction is replaced with the text data “12” after correction. By reflecting the contents edited by the operation unit 2012 on the correction target character in the file as described above, when the corrected data is printed out again as shown in FIG. 29, the correction intended by the user is performed. The contents can be reflected in the output.

  In addition, when a plurality of data corresponds to the pattern in the process of searching the pattern that matches the text data extracted by the above-mentioned OCR from the data string in FIG. 27, the LCD display unit 2013 is as shown in FIG. And the user gives an instruction to widen the designated range of the marker pen and read the output paper again.

[Second Embodiment]
In the first embodiment, an example is shown in which the modified file is processed and re-outputted from the spool data stored in the system. However, the modified content is stored in the original file on the PC that sent the JOB. A means for reflecting may be used. After the print correction output mode is set on the operation unit 2012, when the output paper is read by the scanner 2070, first, the image data is developed in the RAM 2002 via the scanner image processing unit 2080, and then the LCD display unit 2013. As shown in FIG. 31, JOB information is displayed based on the aforementioned watermark information. In the JOB information, the name of the PC that performed the print output, the file name, the number of pages, and the like are displayed. If there is no problem with the displayed contents, the user presses the “Send” button, and another file in which correction is added to the folder or the like of the original file on the PC that sent the JOB via the LAN 2011 is added. Saved by name. If there is a problem with the displayed content, you can manually change the destination setting by pressing the “Modify” button. By having this function, it becomes possible to automatically update the original data. However, in this embodiment, when there is a possibility of correcting the print data, unlike the spool at the time of normal printing, the data itself created by the application is transferred to the system according to the specification at the time of output on the PC. Suppose that the present system performs all the steps to develop the bitmap data. After conversion into PDL data during the process, bitmap development may be performed using a raster image processor (RIP) 2060 as usual.
